The Millennium Public Art Gallery presents a programme of regularly changing, curated art exhibitions and events. The exhibitions and programmes feature New Zealand and international artists in both nationally touring and locally curated exhibitions. Many exhibitions are based on works in the Gallery's permanent collection. Community-focused exhibitions are developed in conjunction with other local events and organisations, and present the work of Marlborough artists, iwi and school children. These art projects take place both at the Gallery and in other locations.
Art displayed at the Gallery ranges from paintings, photography and sculpture to a variety of forms of applied arts and craft. Exhibitions are accompanied by public programmes such as artist and curator talks and educational workshops and school holiday events.
The Gallery is also a popular venue for arts sector, community and business events.
A not for profit organisation, governed by a Charitable Trust and professionally managed, the Gallery's operation is supported by an extensive network of volunteers. The Gallery is partly funded by the Marlborough District Council and to generate additional funds to support the Gallery's programmes; annual fundraising events are held and books, cards, local art and jewellery are available to purchase in the gallery shop.
